Explanation	[[Explanation::This woman is experiencing symptoms of menopause which include mood swings, irritability. Other symptoms may include: depression, fatigue, memory loss, hot flushes, night sweats, vaginal dryness, e.t.c. Menopause, whose average age of onset is 50 years, is a cessation of estrogen production due to a decreased number of ovarian follicles. Menopause can also be described as the permanent cessation of the primary functions of the ovaries - the ripening and release of ova and the release of hormones that cause both the creation of the uterine lining, and the subsequent shedding of the uterine lining. Postmenopausal women have low estrogen levels but high levels of LH, FSH, and GnRH due to the lack of negative feedback on the anterior pituitary and hypothalamus. The ovaries produce estrogens; anterior pituitary gland produce LH and FSH while the hypothalamus releases GnRH. Menopause can be managed with hormone replacement therapy. Educational objective: Menopause is the permanent cessation of estrogen production due to a decreased number of ovarian follicles. Symptoms of menopause may be as subtle as having only mood swings and emotional lability. Postmenopausal women have low estrogen levels but high levels of LH, FSH, and GnRH due to the lack of negative feedback on the anterior pituitary and hypothalamus Educational Objective: References: ]]
